Phil Collins’ ex-wife is in a bitter divorce battle with her investment banker husband.

Just days after it emerged Orianne Cevey, 43, and the Genesis singer had rekindled their romance, papers filed in Miami show she now wants to end her marriage to Moroccan-born Charles Fouad Mejjati – the father of her five-year-old son.

Court documents say the couple have been “separated and living apart” and outline a dispute over the ownership of a £6million Miami Beach mansion she bought for the two of them in 2012. Orianne, Collins’ third wife, wants to nullify an out-of-court marital settlement agreement she and her second husband signed in May last year, which transferred the ­property into his name.

The documents say she could not remember signing over the property because she was on painkillers for a botched back operation.

The complaint reads: “She has no recollection of ever signing before it was recorded in the Miami-Dade County public record, transferring to the husband the wife’s interest in and to the marital residence.”

A source close to Collins, 65, said Orianne, her two sons with the rocker and her young son with Mejjati have been living together in Miami Beach since last summer, – six years after he paid her a £25million divorce settlement.

Mejjati has yet to hire a lawyer and respond to the divorce filing, according to the court records.
